Abstract
Composite resins produced from chemical reactions among a polyglycol epoxide liquid epoxy resin, an aminosilane, tri- and/or tetra-alkoxysilanes and an isocyanate. The hybrid compositions are prepared by an in situ sol-gel process where components of the composition are mixed together sequentially. The composite resins are formed by a coupling reaction between the epoxide groups of the epoxy resin and the amino groups of the aminosilane. The silanes are hydrolyzed to form silanol groups which then undergo polycondensation to form an inorganic polymeric network of an intermediate. Finally, urethane moieties are introduced to the composite resins when unreacted hydroxyl groups from the intermediate react with the isocyanate. These composite resins are evaluated as protective coatings of mild steel substrates, including mechanical strength, anticorrosiveness in a saline medium, and adhesiveness to the mild steel substrates.
